3M™ fire barrier strips fs-195+ firestop can be installed into such a wide-range of applications because of its convenient wrappable strip construction - the flexible elasotomeric firestop material comes in strips which can be quickly and easily wrapped around the penetration. Technicians simply apply the strip, cut it with common tools, secure it in place with steel-wire or composite sheet CS-195+ and seal it with materials such as 3M™ fire barrier CP25WB caulk or moldable Putty. It is designed for excellent weatherability against temperature and humidity and is re-enterable to save added time and material costs after installation.
